A three-step synthesis of 4,9-dimethoxy-1H-benz[f]indole (4) starting from 1,4-dimethoxy-2-aminonaphthalene (1) is described. Compound 1 was condensed with epichlorohydrin in acidic methanolic solution and the crude reaction product, purified by column chromatography, was cyclized to compound 3 by reflux heating in bromobenzene solution in the presence of excess diethylaniline. Appropriate oxidization
的三步合成4,9-二甲氧基-1- ħ苯并〔˚F ]吲哚(4)由1,4-二甲氧基-2-氨基萘开始(1)进行说明。将化合物1与环氧氯丙烷在酸性甲醇溶液中缩合,并将通过柱色谱法纯化的粗反应产物在过量的二乙基苯胺存在下,通过在溴苯溶液中回流加热而环化成化合物3。在碱性溶液中用高碘酸盐适当氧化,得到标题化合物4。
